The reaction given is:

4Ga + P4 ---> 4GaP

The oxidation number of the reactants is zero, because they are pure elements.

The P in compounds may have oxidation states 3- or 5-. Gallium may only have oxidation state 3+.

Then, to be neutral in GaP the oxidation states are 3+ for Ga and 3- for P.

And the transference of electrons can be see in this oxidation - reduction equations:

Ga (0) - 3 e-    ----> Ga (3+)

P (0) + 3e- ---> P (3-)

So, for one formula unit, 3 electrons have been transfered from each Ga atom to P atom to form one GaP unit.

Answer: 3 electrons.

Answer:

C. results when an alkaline-earth metal loses one of its outermost electrons

Explanation:

An ion can be said to result when an alkaline - earth metal loses one of its outermost electrons.

Ions are charged substances that takes part in chemical reaction.

  • An an atom is neutral substance that is a component of an element.
  • An ion is charged substance.
  • In an ion, the number protons and electrons are unbalanced.
  • The number of protons in an atom are the positively charged particles.
  • The number of electrons are the negatively charged particles.

When there is an inequality between the number of protons and electrons within an atom, an ion forms.
